MY name is Erik from Northeast,Pa. We just purchased a 2005 Fleetwood Discovery 35 ft. w/ 3 slides, 330 hp Cat. diesel C7 and wanted to know if there are any major issues w/ this particular model ? We did purchase a extended warranty that covers everything for 3 yrs. including the tires. Just wanting some feed back on the motorhome and introduce myself. Also considering putting a chip to improve the fuel mileage, wanting any feedback w/ that as well. I have done some research and I've heard some stories about the radiator, fuel injectors, etc. Just looking for some advice and or helpful hints w/ this particular model.
